| Ancient Amazon Actually Highly Urbanized In 1925 British adventurer Colonel Percy Fawcett disappeared into the wilds of the Amazon, never to be heard from again after going there in search of a lost city he called Z. But decades later, a city of sorts--actually a series of settlements connected by roads--has been found at the headwaters of the Xingu River where Fawcett went missing in an area previously buried beneath the dense foliage in what is now Xingu National Park.View slideshow here.

Neandertal Mitochondrial DNA Sequenced [The following is an exact transcript of this podcast.]Neandertals were our closest relatives. And now we know a lot more about them. Because researchers have for the first time sequenced a complete Neandertal genome--that of their mitochondrial DNA. The study appears in the August 8th issue of the journal Cell.

Great Chicago Fire begins On this day in 1871, flames spark in the Chicago barn of Patrick and Catherine O'Leary, igniting a 2-day blaze that kills between 200 and 300 people, destroys 17,450 buildings,leaves 100,000 homeless and causes an estimated $200 million (in 1871 dollars; $3 billion in 2007 dollars) in damages. Legend has it that a cow kicked over a lantern in the O'Leary barn and started the fire, but other theories hold that humans or even a comet may have been responsible for the event that left four square miles of the Windy City, including its business district, in ruins. Dry weather and an abundance of wooden buildings, streets and sidewalks made Chicago vulnerable to fire. The city averaged two fires per day in 1870; there were 20 fires throughout Chicago the week before the Great Fire of 1871. Despite the fire's devastation, much of Chicago's physical infrastructure, including its water, sewage and transportation systems, remained intact. Reconstruction efforts began quickly and spurred great economic development and population growth, as architects laid the foundation for a modern city featuring the world's first skyscrapers. At the time of the fire, Chicago's population was approximately 324,000; within nine years,there were 500,000 Chicagoans. By 1893, the city was a major economic and transportation hub with an estimated population of 1.5 million. That same year, Chicago was chosen to host the World's Columbian Exposition, a major tourist attraction visited by 27.5 million people, or approximately half the U.S. population at the time. In 1997, the Chicago City Council exonerated Mrs. O'Leary and her cow. She turned into a recluse after the fire, and died in 1895. history.com |
Columbus reaches the New World After sailing across the Atlantic Ocean, Italian explorer Christopher Columbus sights a Bahamian island, believing he has reached East Asia. His expedition went ashore the same day and claimed the land for Isabella and Ferdinand of Spain, who sponsored his attempt to find a western ocean route to China, India, and the fabled gold and spice islands of Asia.Columbus was born in Genoa, Italy, in 1451. Little is known of his early life, but he worked as a seaman and then a maritime entrepreneur. He became obsessed with the possibility of pioneering a western sea route to Cathay (China), India, and the gold and spice islands of Asia. At the time, Europeans knew no direct sea route to southern Asia, and the route via Egypt and the Red Sea was closed to Europeans by the Ottoman Empire, as were many land routes. Contrary to popular legend, educated Europeans of Columbus' day did believe that the world was round, as argued by St. Isidore in the seventh century. However, Columbus, and most others, underestimated the world's size, calculating that East Asia must lie approximately where North America sits on the globe (they did not yet know that the Pacific Ocean existed).With only the Atlantic Ocean, he thought, lying between Europe and the riches of the East Indies, Columbus met with King John II of Portugal and tried to persuade him to back his "Enterprise of the Indies," as he called his plan. He was rebuffed and went to Spain, where he was also rejected at least twice by King Ferdinand and Queen Isabella. However, after the Spanish conquest of the Moorish kingdom of Granada in January 1492, the Spanish monarchs, flush with victory, agreed to support his voyage.On August 3, 1492, Columbus set sail from Palos, Spain, with three small ships, the Santa Maria, the Pinta, and the Nina. On October 12, the expedition reached land, probably Watling Island in the Bahamas. Later that month, Columbus sighted Cuba, which he thought was mainland China, and in December the expedition landed on Hispaniola, which Columbus thought might be Japan. He established a small colony there with 39 of his men. The explorer returned to Spain with gold, spices, and "Indian" captives in March 1493 and was received with the highest honors by the Spanish court. He was the first European to explore the Americas since the Vikings set up colonies in Greenland and Newfoundland in the 10th century.During his lifetime, Columbus led a total of four expeditions to the New World, discovering various Caribbean islands, the Gulf of Mexico, and the South and Central American mainlands, but he never accomplished his original goal—a western ocean route to the great cities of Asia. Columbus died in Spain in 1506 without realizing the great scope of what he did achieve: He had discovered for Europe the New World, whose riches over the next century would help make Spain the wealthiest and most powerful nation on earth. history.com |
